An underwater cave diving team experiences a life-threatening crisis during an expedition to the unexplored and least accessible cave system in the world.
Some gorgeous cinematography isn't enough to overcome an unoriginal story filled with insipid characters doing ridiculous things.
Wow... that was... that was fucking awful! A group of insufferable douche bags get trapped in a cave and act like dicks to the one the person who obviously has the ability to get them out alive. I don't remember when last I found myself groaning every single time someone, anyone, opened their mouth in a movie. This is an epic waste.
